Level 1 vs Level 2: Is an Upgrade Worth It?

If you drive more than 40 km/day or share a vehicle between two drivers, Level 2 is essential — Level 1 simply cannot restore enough range overnight. For occasional EV users driving under 40 km daily, Level 1 may be adequate, but most Ontario EV owners upgrade within the first year.

Panel Requirements: Do You Need an Upgrade?

A Level 2 charger at 40A draws a sustained 32A load — requiring a dedicated 40A or 50A circuit. Older Ontario homes with 100A service panels often lack available capacity when you account for existing loads (HVAC, electric range, dryer). A licensed electrician will assess your panel and determine whether a 200A upgrade is required. Panel upgrades add $2,000–$4,500 to the total project but are eligible for federal rebates (see our rebates guide).

Every EV charger installation in Ontario requires an ESA (Electrical Safety Authority) permit. Your electrician applies for the permit before work begins, does the installation, then books an ESA inspection. The inspector verifies the circuit is properly sized, the breaker is correct, and the charger is properly bonded and grounded. The whole process adds 1–3 weeks for inspection scheduling, though the physical installation is usually complete in 2–4 hours.
